Refinery Wastewater Treatment using Heavy Canadian Crude for Feed Stock

摘要

Refineries using Canadian Crude as feed stock are experiencing high emulsion wastewater from Desalter mud wash operation. This waste is high in COD/BOD loading Shocking the aeration system by scavenging dissolved oxygen in the system and resulting in misoperation and NPDES exceedences. Emulsion also plugs the aeration diffusers and further adversely impact the Oxygen Transfer rate and efficient mixing of the mixed liquor suspended solids. Fluor technology can process the mudwash in efficient and cost effective way than all other technologies available at this time in the market.
